-The to-be-signed blob challenge is made from these parts: www.example.com using port 8080, the nonce is '1123123123', the algorithm for signing is RSA-SHA256, the key identifier is 123, and finally the challenge is '68147c97-461b-4310-be9b-4c707237ab53'.

 A client would receive this header, extract the challenge, sign it with their private key that corresponds to key identifier 123 in our example using RSA-SHA256, and then send the result in the `Authorization` header as a dot-separated key id, challenge, nonce, and signature.
